To all whom it may concern:

Be it known that I, Gnonen T. MORRIS, .a citizen of the United States, and resident of Missoula, in the county of Missoula and State of Montana, have invented certain new and useful Improvements in Adjustabl Doorstops, of which the following is a specification.

My invention relates to door stops, and it consists in the combinations, constructions and arrangements herein described and claimed. i

An object of my invention is to provide a door stop of simplified construction which is readily adjustable to effect the stopping of a door to which applied at variouspredetermined points in its swinging movement from closed toward fully open position.

A further object of my invention iswto provide a device of the character described which can be operatively applied to a door and frame construction without any extensive changes from the conventional being required in the latter.

A still further object of my invention is to provide a device of the character, described which can be manufactured cheaply and which is thoroughly practical commercially. t a 1 Other objects and advantages wlllber apparent from thefollowing description,- and the novel features of the invention willbe particularly outlined in the appended claims.

My invention is illustrated in the accompanyingdrawings, forming a part of this application, in which Figure 1 is a fragmentary horizontal section through a door and frame equipped with a practical embodiment of the'invention. V t

Figure 2 is a view similar to Fig. 1, showing the door at the end oflthe possiblexmovement toward fully opened position :permitted by one adjustment of theembodiment of the invention, 1

Figure 3 is a plan :view of the devicedetached, portions thereof being broken away and other portions being-shown in section, Figure 4 is a section along th line 4- of Figure 3,

Figure 5 is a perspective view of a bush comprised in the device,

,, Figure 6 is a view similarito Figure 2,

inthe arcof a circle of'which the major portion'of the connector is a chord.

"In the form-of the device illustrated in Figures 1 to 5 inclusive of the drawings, the pair of stop plates are indicated at 1, 1 and the adjustable connector is indicated generallyat 2. The stop plates 1, 1 are substantiallyrectangularin formand are securedin flatwisecontiguous relation in confronting recesses 3 and l'in a door 5 and a support 6 therefor, respectively. The stop plates '1,-1 are provided with registering" diametrically equal openings I 7, 7 therethrough' at the approximate centers thereof. Thelope-nings 7, 7 are concentric with a bore or socket 8 xtending from the cavity 3 into the door 5 and with a' bole'or socket 9 extendingufrom thecavity 4 through or into the support or frame member 6. Similar bushes-or liners 10, 10are disposed in the bores or sockets 8 and 9. Eachofthe bushes or liners 10is provided with aflange 11 at one-end thereof and the bushes or liners are arranged'in the respective bores or sockets so that the flanges 10 are clamped by the stop plates 1, 1 against the adj acent'ends of thebore's or sockets, and are thus held in position.- a v The c0nector-2 comprises a stem consisting of longitudinal sections 12 and 13' respectivelywhich sections are substantially straight from their proximateends forthe V greater part 'of their length and are then turned laterally at an angle of approximately 45-Pand are-merged into head portions 14,15,

which head portions are preciselyidentical in-tessential respects and are diametrically larger tthan th'e openings 7 through the stop plates, for'a purpose which willhereinafter appearm-AT-he sections 12 and 13"are= slidable longitudinally in respect'to each other, the

section 12 being provided'with-apair of guide flanges 16, 16 at the side edges of the end portion thereof proximate to the section 13 be tween which the straight portion of the section 13 may slide axially on the straight portion of the section 12. A set screw 17 extends through a longitudinal slot 18 in the straight portion of the section 13 and thre-'ad-' edly engages the section 12, whereby the section 13 can be releasably clamped against the section 12 and the effective length of, the connector 2 thus adjusted within the limits set by the length of the slot 18.

The heads 14: and 15 are preferably substantially hemispherical or plano-convex in form, the curved or convexed portions therei of being merged into the sections of the stem at the ends of axes passing through the centers of the fiat portions of the heads. The openings 7, 7 through the stop plates are beveled at'their remote ends to provide seats 19, 19 for the curved portions of the heads 14 and 15- when the stop plates have been application of the device illustratedin Figures land 2, the stop plates 1, 1 also constitute the cooperating leaves of a hinge 21 which is one of the hinges employed to swingingly support the door 5 uponthe frame member or support 6. The stemof the connector is arranged to extend through the openings 7 7 of the stop plates so that the heads 14 and 15 will be disp'osedin the axially aligned bushes 10, 10 which line the bores or sockets formed in the portions of the door and support which are in abutting relation when the door is in closed'position. The sections 12and 13 of the stem of the connector are secured together by: means of the set screws 17 to adjust the length of the connector so that the heads will rest in the seats 19,- 19 when the door 5 has been swung position. Obviously, further movement of the door toward fully open position is prevented.

The device is simple in construction and can be adjusted to stop the door at various points in its travel toward openposition so that the door cannot be swung against articles of furniture or the like located beyond the limitof travel determined by the adjustment of the connector. When the door is in closed position", the device is hidden from view and is protected from injuryr A In the embodiment of the invention illustrated in Figures 6 and 7, a pair-"of stop plates 30-'-30 are employed; which stop plates are identical in essential respects with the stop plates 1, 1 but do not constitute ele ments of a hinge employed in swingingly supporting a door 31 upon a frame 32, separate hinges, such as indicated at 33 being used for that purpose. Thestop plates 30-30 are provided with the openings 7, 7 therethrough, as heretofore described and are also formed with a plurality of openings 34 through which screws or like fastening means may be projected to secure the plates in the cavities 3 and a of the door and the frame member or support 31 and 32 respectively.

' A further description of the form of the device illustrated in Figures 6 and 7 or of the application thereof is deemed unnecessary since like parts have been designated by the same reference characters throughout the several views of the drawings.

f Obviously my invention is susceptible of embodiment in forms other than those illustrated in the accompanying drawings. and I therefore consider as my own all modifications and adaptations of the forms of the device disclosed herein, which fairly fall within the scope of the appended claims.

I claim: 1. A device of the character described comprising'a pair of stop plates having openingstherethrough in confronting relation,

and connector comprising a rigid stem consistingof two separable sections provided at their remote ends with portions of such size as to be incapable of movement through the openings of the stopplates, said stem being arranged to extend through said confronting openings whereby the extent of -movement'of the plates apart is limited.

. 2. A device of the character described comprising-a pair of stop plates provided with aligned openings therethrough, and a connector comprising a rigid stem extending through. the openings and being movable in the direction of its length, said stem consisting- 0f two 'separable longitudinal sec-- tions provided at their remote ends with heads of greater diameter than that of the openings through the stop plates. a predetermined distance toward fully open 1 Ardevice of the character described comprising a pair of stop plates provided with aligned openings therethrough, a connector'comprising a stem extending through the openings and being movable in the directionof its length, said stem consisting of two separable longitudinal sections provided at their remoteends with heads of greater diameter than that of the openings through the stop plates, and means for'adment.
